The recycling of wastes from the biological complex for use in life-support systems is discussed. Topics include laboratory equipment, heat treatment of waste materials, mineralization of waste products, methods for production of ammonium hydroxide and nitric acid, the extraction of sodium chloride from mineralized products, and the recovery of nutrient substances for plants from urine.
Experimental data show that weightlessness conditions lasting 5 days or more (18-25) do not produce significant disturbances in physical reactions of astronauts, with the exception of some singularities in functioning of the cardiovascular system: A reduction in heart rate and somewhat large fluctuations in the physiological indicators of cutaneogalvanic reactions.
Biomedical data obtained on men and animals during weightlessness conditions establish instabilities in pulse rate and blood circulation that smooth out in proportion to adaptation to the weightless condition. The unusual slowness of recovery of pulse rate to initial values after space flight stress is attributed to biological simulation of hormonal shifts and discharge of humoral substances into the blood that prevent a rapid recovery of some biological indicators to initial values.
